Hi everyone,
I am attempting to adopt some code to work more reliably then how
it is now...
What I am doing is coding a upload form where people could be
uploading .zip files in excess of 200 MB... Yes I know that is
large, but it's for a print shop and they get HUGE files to print
from.
The code I'm having issues with is this:
$filename = $_FILES['userfile']['name']; // Get the name of
the file (including file extension).
$ext = substr($filename, strpos($filename,'.'), strlen
($filename)-1); // Get the extension from the filename.
All I want to do is grab the file extension and verify that it is
a .zip or a .pdf etc. file. This is working for small files (under
a few megs) but for some reason it fails when I get bigger. I have
increased the allowed memory size to 50 MB's I'm testing with a 44
MB file right now.
When it fails, it says the file type is not allowed even though it
is listed in the file type array.
Hopefully I have given you enough to go on to at least ask me some
questions :)

Looking at what I think you are trying to do, how about this?
<?php
if ( isset( $_FILES ) ) {
foreach ( $_FILES AS $file )
$filename = $file['name'];
list($ext) = array_reverse(explode('.', $filename));
$allowed_ext = array('zip', 'pdf');
if ( in_array($ext, $allowed_ext) ) {
// Correct extension; do what ever
} else {
// Incorrect extension; do nothing
}
}
}
?>
I am somewhat surprised that all code suggestions are rather
complicated in my opinion. What is wrong with 'pathinfo'?
if ( !isset( $_FILES['userfile']['name'] ) ) {
echo "No file has been uploaded";
} else {
$allowed_extensions = array( "zip", "pdf", "ai", "html" );
$file_info = pathinfo( $_FILES['userfile']['name'] );
if ( in_array( strtolower( $file_info['extension'] ),
$allowed_extensions ) ) {
echo "File has a valid extension";
} else {
// do something else
}
}
// frank
